From generating human capital to transformative education: discursive struggles in Spanish education policy and openings for sustainability

Education is considered a key leverage point for sustainability transformation. Yet, dominant human-capital-based discourses, promoted by actors such as the OECD, have long framed education in an economistic way, marginalizing the creative, critical, and transdisciplinary pedagogies required for sustainability. Using the case of Spain, we apply discourse analysis to analyse historically (1975 to the present) how human-capital-based discourses have shaped education policy and where opportunities and constraints for transformative sustainability education (TSE) emerge. The findings reveal three major periods: (1) emancipatory aspirations during Spain’s democratic transition (1975–1990), (2) consolidation of a neoliberal consensus shaped by OECD discourse (1990–2018), and (3) the emergence of discursive openings for TSE (2019–present). While in the last period sustainability has become a central signifier with an education law that legitimises transdisciplinary, experiential and embodied pedagogies, its implementation remains partly constrained by entrenched neoliberal governance. The analysis of these discursive shifts reveals key opportunities and barriers for transformative shifts in education systems, showing that while dislocatory events and the linking of different struggles for educational reform can enable the introduction of elements of TSE into policy, the strong persistence of market-oriented logics risks leading to a co-optation of sustainability.
